Is deep space travel a step closer to reality? Nasa reveals successful test of ‘impossible’ fuel-free engine that breaks the laws of physics
EM Drive Fuel-free engine could take a spacecraft to Mars in 10 weeks
Creates thrust by bouncing microwaves in chamber, using solar power
Nasa has conducted more tests using an improved experimental process
Test designed to remove errors from earlier study but still produced thrust
Scientists still aren’t sure how this happens as it defies the laws of physics
